DOOR-CHECK.
Specification of Letters Patent.
Patented Dec. 22, 1911.
Application filed March 24, 1914. Serial No. 826,958. 7
To all whom it may concern Be it known that I, THOMAS A. LAWLER, a citizen of the United States of America, residing at Granville, in the county of \Vashington and State of New York, have invented new and useful Improvements in Door-Checks, of which the following is a specification.
The general object of this invention is to effect the cushioning of a door immediately prior to the closing of the same.
Another object is the provision of a door check which may be arranged on the door jamb with one of the parts projecting slightly in advance of the other so that the door will abut the same when moving into closed position. And to these ends the invention consists of telescoping sections, one of which is provided with a striking plate and the other being adapted to be secured to a door or door-casing and resilient means for positioning the sections in extended relation with each other.
Other objects will appear and be better understood from that embodiment of my invention of which the followingis a specification, reference being had to the accompanying drawings forming part hereof, in which Figure 1 is a side view of the device. Fig. 2 is a longitudinal sectional view taken on the line 2 2 in Fig. 1. Fig. 3 is a cross sectional view taken on the line 33 in Fig. 1. Fig. 4: is a detail perspective View of the striking plate section.
As shown in the drawings the invention is composed of the telescoping members 5 and 6 which are held yieldingly extended by the spring 7. The members 5 and 6 may be formed of any suitable material such as brass, steel or the like, and are preferably cylindrical in structure, but it will be noted that the member 6 is not a true cylinder, as it is open at one side as indicated by 8 for the purpose of being slidingly mounted on the member 5. The member 5 is provided with longitudinal grooves 9-9 at either side, which are adapted to receive the ribs 1010 formed on the member 6. Therefore, it will be seen that the two members can only be moved in longitudinal relation and by virtue of the rib and groove connection.
The member 5 is provided with laterally disposed attaching ears 11 which are perforated for the reception of the screws 12, so that the device may be positioned on a door or door-casing. The member 6 is provided at its front end with the striking plate 13, upon which is mounted a suitably resilient head 14 which is preferably formed of rubber or the like, so that upon a polished surface striking thereagainst, the polish will not be defaced or marred.
As shown in Fig. 2, the overlapping or meeting ends of the members are open, therefore it will be seen that the spring 7 may be housed within the two sections, and by hearing against the interior sides of the remote ends, to which it is secured as by soldering or otherwise, the spring retains the two members normally extended.
In practice the device may be secured to either a door or door casing, and is arranged so that the striking plate 13, extends beyond the structure to which the device is secured. Thus, if the device is positioned on the door casing, the plate 13 will extend beyond the face of the casing by reason of the spring, and upon a door closing forcibly, the door is adapted to strike against the head 14:, and the shock be taken up by the spring 7.
What is claimed as new is:
A door check comprising a pair of telescoping members having overlapping open ends and closed remote ends, one of said members being provided with longitudinal ribs, the other member being provided with longitudinal grooves receiving the said ribs, one of the said members being provided with attaching lugs, the other member being provided at its end with a striking plate, and a coil spring housed within the members for retaining the same normally extended substantially as described.
In testimony whereof I afiix my signature in presence of two witnesses.
THOMAS A. LAWLER.
